Hi I was wondering what the state of multi-chamber on a single arduino was? I saw references to that being started on but I’m not seeing anything in the documentation about how to get it working.
Right now I’ve got a single Arduino Uno and an 8x 10A SSR board and a bunch of ds18b20 temp sensors going into it. The Uno has enough pins to control the SSRs and the temp sensors come in on the onewire bus so it seems to me the only thing stopping this from being able to control 8 separate chambers is the multiple PID cycles being defined on the Uno… of course I have no idea how hard that would be to implement. So I’m just wondering if this setup is possible in perhaps a Dev build or if multiple chambers is only going to be supported on the Spark.
(also, for background, I want do to this because I’m building a Glycol Chiller to service multiple fermentors; I want one of the chambers to be a probe in the Glycol and SSR switching in “Fridge Constant Mode” or whatever to keep the Glycol at ~22F, and then another chamber setup with a probe in the thermowell, an SSR for cooling via a submersible pump circulating glycol in the jacketing, and an SSR for a heater attached to the vessel, and I want to use those to keep the beer at a profiled temp.)
So, what are my options right now?
